I am starting this thread because I want to collect stories, ideas, successes and failures about running the HEDT cpu's from AMD into one thread.

I know that Kevin Olley https://setiathome.berkeley.edu/show_user.php?userid=35215 and Keith Myers https://setiathome.berkeley.edu/show_user.php?userid=14084 are both on the first page of the LeaderBoard as well as running multi-core AMD cpus. Does anyone else want to join in?

Apparently, the latest generation AMD's run hot when they are OverClocking. And AMD has set them up to automatically overclock (I think) if there is thermal "headroom." If they are not overclocking, I think they use less power than the equivalent Intel cpus?

So there should be some stories about CPU coolers in this mix too.

My own story on this topic starts with getting a "new" and unboxed 2990WX off eBay for $1,550. It turns out it was also missing a cooling adaptor bracket.

Just about every cooling solution https://www.amd.com/en/thermal-solutions-threadripper and
https://www.tomshardware.com/news/air-liquid-cooler-threadripper-2,37588.html that I was attracted to was out of stock on NewEgg and Amazon.

And the first "recertified" MB I ever bought from NewEgg will not boot (the last MB I bought from NewEgg was an "open box" with a significant discount). It stalls at "CO" during boot and it won't do a blind non-cpu bios flash+ update that the manual says it will do. No blinky LED like the directions call for :(

My Nephew appears to have found an affordable liquid cooler that doesn't need the above cooling bracket.

I think I will try MSI's tech support before I return my "recertified" MSI MB. I may have to buy a new "sTR4" MB or wait till January or so for some lower cost, debugged TR2 MB's to come out?

Not sure what "cooling bracket" you are referring to. Are you talking about the Asetek adapter ring for the ubiquitous AIO AIB branded coolers? None of those are full coverage cold plates. You should always use a full coverage cold plate that covers the entire IHS with ThreadRipper.

One of the best out of the box and available at TR launch was the Enermax Liqtech TR4 360mm AIO. It had a full coverage cold plate from the beginning. It is now on version II and is improved with a more powerful pump and better optimized flowplate. Now with RGB too if you care about that sort of thing. It has kept its price the same since the beginning too. Available now at Newegg.

Enermax Liqtech TR4 II 360 Addressable RGB AIO Liquid CPU Cooler, Support 500W+TDP, Overclocking, AMD Socket TR4 Ready, ELC-LTTRTO360-TBP

[Edit] It doesn't need an adapter bracket. It just mounts to the stock socket threaded holes with hardware included with the kit.

Pretty much the entire Ryzen architecture has minimal overclocking headroom. What is possible does not scale well with voltage. With increased voltage comes exponential power consumption. The new improved Ryzen+ architecture mainly made improvements to reduced latency in CCX-CCX communication and improved memory compatibility at increased memory timings and clocks. This is the most important improvement since CCX-CCX communications on the Infinity Fabric bus happens at memory core clock speeds. So if you can run faster memory clocks, it speeds up the entire chip and system.

There is also new and improved "automatic overclocking" mechanisms for Ryzen+ with the XFR2 and Performance Boost2 algorithms. When the power, TDP and thermal headroom allows, the chip will automatically boost one or all of the cores from stock speeds. Depending on your workload, it is commonly easier to just run stock Auto settings and let the chip do what it can to maintain the highest clocks on all cores. For a heavily loaded system utilizing 80-100% of the chips capabilities, it is sometimes better to manually set a defined all-core clock that is higher than the stock base frequency. If you have the thermal cooling solutions to allow. Still better to stick to Auto voltages or use the Offset method to keep voltages to a reasonable value for 24/7 loads.

AMD with Ryzen and ThreadRipper continue to offer a great "bang for the buck" computing solution that is offered for many years of support without having to purchase the latest motherboard platform as you have to do for each new Intel released family.

Regarding your power consumption observation, I wanted to offer a comment regarding my two platforms. I have a Intel X99 HEDT mobo with a i7-6850K 6C/12T cpu. I run an all-core overclock of 4.25Ghz @ 1.25V over the base 3.6Ghz stock frequencies. Even with C-States enabled, the system idles at 330W when BOINC is not running and the system is just idling at the desktop.

The Ryzen+ systems with their 8C/16T cpus @ 4Ghz and Auto voltages of 1.30V on X470 motherboards idle at 120W when BOINC is not running and idling at the desktop. So I pay for a lot more power on outage Tuesdays when the systems run out of work for the Intel system. For the long outages, I turn off the Intel host to conserve power while waiting for the project to come back. I don't bother with the AMD hosts.

All CPUs run hot when overclocked. Every last one of them. That's why over-clockers use such heavy duty cooling systems- to get rid of the extra heat.

If they are not overclocking, I think they use less power than the equivalent Intel cpus?

Intel CPUs are still more power efficient than AMD, but that difference is much smaller than it used to be, particularly for the high core count models.

MSI tech support recommended trying another flash drive for my "blind bios upgrade" and it did! So now I am waiting on the cpu cooler.

I think that is what I just ordered from NewEgg.

Very surprised how well the Noctua air coolers performed.

Yes, I expect those 2990WX hosts to be climbing up the charts. Sheer numbers overwhelm all eventually. Same goes for cpu cores as well as gpus.

I'm only using a consumer chip - the 2600X - on my home rig while I'm at work but this might be handy for anyone trying to balance thermals and performance with Ryzen or Threadripper rigs. This is for the gen 1 chips, not sure how much it's changed with the gen2 as the architecture itself didn't change much, but it should have changed at least a little with the change from 14nm to 12nm.



Power consumption (and therefore heat) is roughly correlated to frequency*(voltage^2), so as soon as you have to start piling on the voltage after passing 3.9Ghz, the power consumption starts sky rocketing for fairly small gains. In some cases it might be better to lock the frequency to 3.9 or lower just for efficiency's sake. At 3.3Ghz (scores about 3.5 using the previous model) you can run at about half the power consumption of the ~4Ghz all-core boost (about 7.9 using the same model).

Edit to add source : worth a read.

Would it be possible to scale down that image a bit?
The forums haven't been working well with large images lately.

Oops.

Edit button's disappeared for me - I'm guessing there's a time limit there?

Yep, although you actually need to change the size of the original image.
1132 * 679 would be better.
755 * 453 would probably be best.

Hi Zoom,

Yep, they changed it to 1 hour back in the day when too many people were abusing it and repeatedly editing a post. I believe there was some other reason for it too, but cannot remember what it might be (memory go bad with age). ;)

Have a great day! :)

This one is mine! It was originally running with a 1950X, but just upgraded to the 2990WX last month. It is the Zenith Extreme MB, with 32G of 2400 ECC udimm. I am running it with the rev2 EK Monoblock. I have it at 3.2GHz with Vcore of 1.092V (measured at ProbeIT point). I run with LLC set to level -L1. Memory voltage slightly higher than spec at 1.21V. I also increase SOC voltage slightly. I have CPU PCIe at GEN2. CPB and SMT are off. It runs at about 58C and VRMs are confirmed to be below 40C (measured on block near VRM). I have changed my strategy from heavy OC to minimal OC in order to manage power. My focus now is more cores at lower voltage to maximize contribution for the money spent on power.

I have disabled SMT due to significant slow down, especially GPU tasks when enabled. Single thread on all 32 cores is not an issue. Running PCIe at GEN2 due to errors in dmesg concern PCIe. Getting a stable OC was a different experience than any other CPU I have worked with. System instability was it running very slowly and producing good results after more than 24hrs of running normally. Probably the issue was something other than core stability. This is why I increased SOC voltage and changed to PCIe GEN2.

I would like to see how the Threadripper performs with the new app i made available on my website.
Sadly the 2990WX runs on Linux.

The 2990W I have coming online "soon" is reusing a dual-boot Win10 and Lubuntu HD. I assume I would need an upgrade to the Lunatics distro to test your newest crunching app?

I will only OC using the standard options at this time.
